on my 2K M roadster. The kit is very easy to install. Don't know if there is any power increase but it sure sounds great at full throttle. The only negative I noticed is that at part throttle you can sometimes hear a little bit of a whistle caused by the throttle body. After having several sports cars over the years I bought it more for the intake sound of an older sports or performance car. If the sound would bother you the Dinan might be quieter alternative. Good luck, CK
